Accidentely one day I closed my laptop while on live and the internet. I opened up my laptop and then my internet wasn't working nor was my live. I took my laptop to the tech department to get my internet working again. They could do that. When I got back to my room, my shared tab was gone. I can no longer connect my xbox 360 to my computer. My computer wont evern recognize my xbox 360. I am very angry. I don't know if it has to do with the school internet connection now or what, but I would appreciate any help!
